"More times than not, when Im up 4-1, I close it out," said Isner, who is 5-0 in his three-set matches this season but is playing in his first tournament since exiting the Australian Open with an ankle injury last month.

Williams ousted wild-card Marcos Baghdatis of Cyprus 6-7 (7), 6-4, 6-2 in Thursdays nightcap to reach his second ATP quarterfinal.

Nishikori was trailing Teymuraz Gabashvili of Russia 4-2 when he decided to stop the match. He said that he experienced discomfort for the first time during his first-round win Tuesday in which he stretched his win-loss record this season to 12-2. "I tried to play, but if youre not 100 per cent, its tough," said Nishikori, who is ranked No. 15 in the world and was coming off a win in Memphis last week. "I couldnt do anything today. Its going to take some time to recover. Its shocking this happened, especially since Ive been playing well."
